What is the HS code for air shower cleanroom?

air shower cleanrooms are vital components in industries where contamination control is crucial, such as pharmaceuticals, Electronics, and biotechnology. These air shower systems are designed to remove particles, dust, and contaminants from personnel and materials before entering ISO 8 cleanrooms. When importing or exporting air shower cleanrooms, understanding the correct HS (Harmonized System) code is essential for customs clearance and proper classification. This article explains the HS code for air shower cleanrooms and its relevance in global trade.

What is the HS Code for Air Shower Cleanroom?

The HS code for air shower cleanrooms falls under the category of "machinery" in the Harmonized System, used for international trade. The specific classification ensures that these items are correctly identified for customs purposes.

HS Code Classification

The HS code for air shower cleanrooms is typically 8414.59, which covers air conditioning machines, including air purifiers and Ventilation systems. This code applies to equipment specifically designed for use in cleanroom environments, where contamination control is a priority.

Purpose of HS Code

The HS code is an international standard used to classify products for customs and trade purposes. By correctly identifying the HS code for air shower cleanrooms, businesses can streamline customs processes and ensure compliance with regulations. The correct classification also helps prevent delays in import/export activities.

Regulatory Compliance

Air shower cleanrooms are subject to specific standards, such as ISO 14644 for cleanrooms and GMP guidelines in pharmaceutical industries. Accurate classification under the HS code helps companies comply with both local and international regulations, making global trade easier.

Importance in Global Trade

Using the correct HS code for air shower cleanrooms ensures that duties, taxes, and shipping costs are calculated correctly. It also simplifies the process of importing and exporting products across different countries, preventing delays or penalties.

Air Shower Air volume and Specifications

Air volume is a critical factor in the performance of air shower systems. Proper specifications ensure that air showers effectively remove contaminants from personnel and materials before they enter cleanroom environments.

1. Airflow Capacity

Air showers are designed to provide high-velocity air jets that remove particles from surfaces. The airflow typically ranges from 3000 to 4000 m³/h(cubic meters per hour) depending on the size and application of the air shower. This is essential for achieving optimal decontamination efficiency.

2. air velocity and Pressure

The air shower's air jets are designed to deliver high-speed airflow, usually between 20 to 30 meters per second. This ensures that contaminants are blown off effectively. Air pressure within the system must be consistent to maintain a steady airflow and prevent contamination buildup.

The specifications of the air volume and airflow pressure directly affect the cleanliness level of the environment. Properly configured air showers can prevent contamination by ensuring all particles are expelled before entry into the iso 6 cleanroom.

Adjustments to airflow may be necessary depending on factors like the size of the air shower or the required level of cleanliness. Customization options are often available to meet specific industry needs.

3. Filtration and Efficiency

Air showers are equipped with HEPA or ULPA filters to ensure that the air is free from contaminants. These filters trap particles as small as **0.3 microns**, providing an additional layer of filtration to prevent any residual contamination in the air.

How to Reduce Pollution with Air Shower?

Stainless Steel:

Air showers constructed from stainless steel are highly effective in reducing pollution because stainless steel is resistant to corrosion and easy to clean. It prevents contamination from accumulating on surfaces, ensuring long-term cleanliness in the air shower.

Steel Plate Paint:

Air showers made from steel plate painted with anti-corrosion coatings further minimize contamination risks. The paint protects against environmental factors, ensuring that the system maintains its structural integrity and does not contribute to particle generation.

Painted surfaces are also easier to clean and maintain, helping to reduce the overall contamination within the cleanroom. These materials help ensure that air showers effectively maintain the cleanliness of sensitive environments like pharmaceutical labs or Semiconductor manufacturing facilities.

Other Material Options:

Other materials such as aluminum or coated steel may also be used to enhance the durability of air showers. The choice of material depends on the level of contamination control required and the operational environment.

Air Shower In and Out Operation Specifications

1. Entry and Exit Protocol

Personnel should enter the air shower through the designated entry door. Upon activation, the system will blow air through nozzles directed at the individual, cleaning their clothing and equipment before they exit through the second door into the cleanroom.

2. Sequential Operation Process

The air shower system operates in a sequential manner:

- First Step: The user enters the air shower and the door is closed.

- Second Step: The air shower jets activate automatically based on the sensor detection. The user remains in the room for the predetermined cycle time, typically 30 to 60 seconds, depending on system settings.

- Third Step: After the decontamination cycle is complete, the exit door can be opened, allowing the user to proceed into the cleanroom.

Proper operation requires that the doors be closed while the air jets are activated to avoid contamination from entering or exiting the room. The air pressure inside the room should be slightly higher than that outside to ensure no particles escape.

The process should be carefully monitored and regularly maintained to ensure it operates smoothly. Airflow velocity, air pressure, and decontamination cycle time are all critical factors to consider for optimal operation.

3. Regulatory Compliance

Ensure that the air shower system meets international standards like ISO 14644 or GMP regulations. These standards set the necessary requirements for air cleanliness, contamination control, and system performance to ensure the highest levels of operational efficiency.

How to Connect Air Showers to Power

Connecting air showers to power is a straightforward process, but it requires attention to detail to ensure safety and compliance with electrical standards.

1. Power Requirements: Air showers typically require a single-phase or three-phase electrical connection, depending on the system size and design. Ensure that the system voltage is compatible with the local power supply before installation.

2. Installation Procedure: Connect the air shower’s power cables to the designated electrical terminals, ensuring that the connections are secure. The installation should be done by a qualified electrician, who will also verify that the wiring complies with local electrical safety codes.

3. Safety Measures: Always install a dedicated circuit for the air shower system to prevent electrical overload. It is important to include a circuit breaker or fuse in the setup for added protection. Regular inspections and maintenance should be conducted to ensure the system operates safely and efficiently.

Summary

By adhering to the correct procedures for installation, maintenance, and operation, air shower cleanrooms can effectively maintain the integrity of cleanroom environments and comply with relevant industry standards.
